| Abstract: | Based on the principle of the DC speed regulation,the Simulink and SimPowerSystems toolbox in the Matlab were applied,and the simulation method facing the system’s structure of electrical principle was used,the double loop-locked system of DC speed control for mining electric excavator were simulated,even more,it was made analysis and comparison.The simulation model and waveform of DC speed control system for the motor were provided.The results verify that the simulation model and the setting of parameter are precision.The simulation results show that the feedback control systems have obvious rigidity,and mechanical properties are vulnerable to interference.Double closed-loop system has good performance on the efficiency and stability. |
